|Abstract: ||two-year field trial was conducted to evaluate the effect of supplemental irrigation on increasing
and stabilizing yield and quality of forage produced by annual ryegrass in southern Portugal. The following four
irrigation treatments were tested: rainfed (control), and irrigation up to 25%,50% and 100% of soil water holding
capacity. In both years, the importance of irrigation was evident in order to increase and stabilize forage
production because even with the lowest amount of water application it was possible to at least double the
number of harvests. Also the best response was reached for the 100% treatment. The beneficial effect of
increasing water application was more noticeable in the second year. Crude protein and digestible dry matter
yields showed similar responses to dry matter yield, except in the first year for crude protein yield, whose values
were not significantly different between the three irrigation treatments.|
